To all whom it may concern:

Be it known that 1, JOHN T. BREWER, a citizen of the United States, residing at Tonkawa, in the county of Kay and State of Oklahoma, have invented certain new and useful Improvements in Acetylene-Gas Generators; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improve ments in acetylene gas generators and relates more particularly to automatic carbid feeding mechanism therefor.

The primary object of the invention is to provide an acetylene gas generator having novelly constructed carbid feeding mechanism which may be automatically operated so as to discharge a quantity of carbid into the water of the generating tank by means of the bell of the gasometer.

The invention also aims to generally improve acetylene gas generators to render them more efficient, practical, and commercially desirable.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a vertical sectional view through the generating tank and gasometer, parts of the apparatus being shown in elevation, Fig. 2 is a vertical sectional view through the carbid holder and feeding mechanism, Fig. 3 is a bottom plan view of the carbid holder and feeding mechanism, Fig. 4 is a top plan View of the feeding mecha nism and casing therefor, Fig. 5 is a bottom plan view of the carbid discharging disk, Fig. 6 is a detail view taken on the plane of line 6-6 of Fig. 4, and, Fig. 7 is a detail view of the rack and gear connection.

Referring in detail to the drawings by numerals, 5 designates the generating tank, 6 the carbid receptacle, and 7 the gasometer. A pipe 8 leads from adjacent the top of the generating tank into the gasometer 7 under the bell 7 9 designates the service pipe.

The carbid receptacle 6 has its lower sec tion in the form of a cylindrical shell or casing '10, which is positioned upon the top of the generating tank. WVithin the casing 10 there is positioned a horizontal wall or partition 11 which is provided with a central opening 12 and an arcuate slot 13.

The carbid discharging disk 14 rotates upon the top of the wall 11 and carries an annular gear 15 which projects through the opening 22- and extends below said wall. The disk is of considerable thickness and is formed with an annular series of pockets 16 which extend entirely through the disk and which are closed at their lower ends by the swinging doors 17 which are pivoted at one of their ends. These doors, when in their closed positions, are disposed entirely within the pockets and rest upon the wall 11.

A cap, generally designated 18, is positioned over the disk 14 and includes an annular rim 19 which is closely fitted against the interior of the casing 10, a plate 20 which carries the rim and which is cut away as indicated by the numeral 21, and an annular band or rim 22. The rim 22 engages the central portion of the disk 14 and the rim 19 engages the upper face adjacent its periphery. An inwardly and downwardly converging band 23 is also provided and is secured at its upper edge to the rim 19 and bears at its lower edge against the top of the disk 14. A housing 24 is secured upon the top of the plate 20 adjacent one end of the recess 21 and the spring-pressed tongue 25 projects into the former through a slot 26. The tongue is held in position by a screw 27 which extends through the top of the housing in the plate 20 and an expansive helical spring 28 surrounds the screw and forces the tongue against said plate. The outer portion of the tongue is extended downwardly and bears against the top of the disk 14. The tongue is somewhat wider than the pockets 16 and therefore is not forced into the same by the action of the spring 28. A flange 29 is carried by the tongue and bears against the inner side of the housing, closing the slot 26.

The cap 18 and discharging disk 14 are held against the wall 11 by means of the screw 30 which is threaded at its lower end into a brace 31, which extends across the casing 10. A shaft 32 extends transversely of the casing 10 under the brace thereof and carries a bevel gear 83 which meshes with a ring gear 12. The other end of the shaft is journaled through the arms of a. U-shaped frame 34 carried upon the stationary portion of the gasometer 7 and carries a ratchet wheel 85 fixed thereto. A gear wheel 36 is loosely mounted on the shaft and carries the pawls 37 which engage the ratchet wheel. The gear wheel 36 is rotated by means of a rack 38 carried by the hell 7 of the gasometer.

Then the bell drops below a predetermined point, the rack 38 is brought into engagement with the gear wheel 36 and rotates the same so as to cause a corresponding ro tation of the shaft 32. The gear wheel 33 carried by the shaft 82 then rotates the distributing disk 14 through the medium of the gear 12. A partial rotation of the disk 1% will bring one of the pockets 16 containing carbid over the slot 13 and the door 17 will swing downwardly through the slot and permit the carbid to discharge into the generating tank. The plate 20 extends over the slot 13 and prevents a continuous flow of carbid through the open pocket. The carbid flowing into the generating tank causes a fresh supply of gas to be generated, which flowing into the gasometer raises the bell 7 so that the rack 38 is returned to its normal position above the gear wheel 36. As the discharging disk is intermittently rotated,

the empty pockets fill as they pass the recess 21 and then are moved under the plate 20 between the rims 22 and 23. The tongue 25 scrapes the upper face of the distributing disk and levels the carbid and prevents more than a known amount being carried by each of the pockets. After the pocket has discharged into the generating tank a further rotation of the disk 14L will draw the depending door against one end of the slot 13 and cause it to swing upwardly into its closed posi't-ion.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that I have provided an acetylene gas generator having carbid feeding means of extremely simple construction and automatic operation.

It is to be understood that while I have shown and described the preferred embodiment of my invention, I do not wish to be limited to this exact construction, combination, and arrangement of parts, but may make such changes as will fall within the spirit and scope of the invention.

Having thus described my invention, what I claim is 1. The combination with a carbid holder having a hollow cylindrical lower portion, of automatic carbid feeding means positioned within said cylindrical portion, comprising a rotatable disk having a plurality of pockets formed therein, swinging doors closing the lower ends of the pockets, a slotted wall upon which the disk rotates, the slot permitting the doors to open as they pass thereover, a plate positioned over the disk so as to prevent a continuous flow of carbid through the pocket when the door thereof is open, the plate being recessed so as to permit the carbid to flow into the empty pockets, and a spring tongue for leveling the carbid within the pockets.

2. In an acetylene gas generator, carbid feeding means including a cylindrical casing, a horizontal disk rotatable therein and formed with pockets, a slotted wall positioned under the disk and permitting the pockets to discharge their contents one at a time as the disk is rotated, a cap disposed over the disk in spaced relationship thereto, inner and outer rims depending from said cap and engaging the top of the disk, the pockets of the disk being disposed be tween said rims, the cap being arcuately recessed so as to permit carbid flowing into the pockets when they are closed, and a spring-pressed tongue carried by the cap and extending downwardly into engagement with the top of the disk, said tongue level.- ing the carbid within the pockets as they approach the discharge point.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN T. BREWER.
